摘要：
A high-pressure discharge lamp includes a luminous tube, an outer bulb housing the luminous tube, and a diffusing film formed on at least one of inner and outer surfaces of the outer bulb, in which the diffusing film includes first silica particles having shapes different in surface curvature from each other and hollow second silica particles.
